BOBBIN.

SPECIFICATION forming part of Letters Patent No. 501,897, dated July418, 1893.

Application filed March 2, 1893. Serial No. 464,349. (No model.)

To @ZZ whom it may concern.-

Beit known that I, GURDON PENDLETON, J r., a citizen of the UnitedStates, residing at Paterson, in the county of Passaic, State of NewJersey, have invented a certain new and useful Improvement in Bobbins,of which the following is a specification.

My invention consists of a novel construction of bobbins for use inspinning on a spindle, or as a take-up or winding bobbin, or on apin-rail as a twist bobbin.

Bobbins have been heretofore made for these purposes of two metal headsdrawn together upon the ends of a cylindrical wooden body or shell by acentral metallic rod or tube Vsecured to the heads.l Solid metallicbobbins have also been contemplated, as well as various otherconstructions, in the attempt to provide a true, perfectly balancedbobbin, which will be unaffected by atmospheric changes, can be easilymanufactured, will take up and give o the threads without catching, andbe otherwise efficient and durablein use. I have attained theseadvantages by my improvement which comprises various novel features ofconstruction which will be described and pointed out in fullhereinafter.

Reference is to be had to the accompanying drawings forming part of thisspecification in which- Figure l is a side, partly sectional View of abobbin constructed in accordance with my invention for use as aspinning, winding, or twist bobbin. Fig. 2 is a longitudinal sectionalview showing the component parts of the said bobbin before union.

Like letters of reference designate corresponding parts in both figures.

As before mentioned, I construct my improved bobbin of two solidcircular metallic heads A, united concentrically to the respective endsof a cylindrical shell B of less diameter than the heads, the latterbeing thereby rigidly united by the shell B, on whichljal's'o the threadis wound.

The cylindrical shell B may be formed from a section of a metallictubing of the proper diameter, but I find it more economical tomaketheshellfrom thin metalcut and stamped or pressed to form twoopposite and exactly equal semi-cylindrical sections B B2, as shown inFig. 2, which when united to the heads A, as in Fig. 1, form thecomplete shell B.

To properly unite the ends of the shell B to the heads A, I form therespective ends of the shell each with a severalty of equi-distantintegral tenons C somewhat longer than the thickness of the heads A,which tenons are preferably cut on the metal of the sections B B2 beforethey are brought into semi-cylin- 6o drical form, and on the inner sidesof the t heads A, I sink concentric circular grooves D, to receive theends of the `shell B, and through the heads in said grooves form morytises E to correspond with and receive the tenons C, which will protrudethrough said mortises. I prefer also to sink like circular grooves F inthe outer sides of the heads A,

to include the said mortises, and I then bring the heads, with theinterlocked shell,between 7o the plates of a press, by which I closelyseat and seal the ends of the shell B in the innerl grooves D, and upsetthe protruding tenons C in the mortises E, the outer grooves F servingto countersink the overflowing metal of the tenons. The heads are thusmost rigidly united by and to the shell B, and the line of union sosealed as to prevent threads from being caught thereby. The bobbin isperfectly rigid, without undue Weight, and being 8o wholly of metal isunaffected by changes of temperature.

To adapt this bobbin both for spinning and as a winding or twist bobbin,the heads A are previously provided with central apertures G, andtubular gudgeons H are provided,with necks H which are tted and alignedin said apertures, and upset on the inside of the heads to fix thegudgeons securely thereon. The gudgeons Il serve as such when the bob-9o bin is used as a winding or take-up bobbin, and also, being tubular,to receive the spindle in spinning, or the pin in the pin-rail intwisting.

When the bobbin is designed forawinding 9 5 or take-up bobbin solely,the gudgeons may be made solid instead of tubular. I may also forspinning purposes form the two gudgeons H of the end portions of anintegral tube, which then need not be upset inside the roc. heads A.

I claim- 1. A bobbin constructed substantially as herein described of aclosed cylindrical metallic shell B, formed with series of end tenons C,two metallic heads Aformed with mortises E, in which the tenons C areupset and with central apertures G, and gudgeons H fixed in saidapertures.

2. A bobbin constructed substantially as herein described of twocentrally apertured metallic heads A, rigidly united by a cylin- [odrical metallic shell B, and gudgeons H formed with reduced necks Hreceived in said apertures in the heads, and upset on the inside of theheads.
